Simple Two Lists RESOLVED

I have 3 ListBoxes.

List1 has A-Z
List2 has A-Z

but i want list3 contain all possible combinations.

so i need to it to take the first letters in list1 being A, then go al the way down list2 adding the letter from list2 to the letter in list1.

So i would end up with

AA
AB
AC
AD
AE
AF
AG etc

BA
BB
BC
BD
BE
BF
BG etc

CA
CB
CC
CD etc

you get the picture i hope.

But it has to use the values loaded in the listboxes using A-Z as an example i wana be able to load differnt words.

VB Code:

Dim i1 As Integer, i2 As Integer
For i1 = 0 To List1.ListCount - 1
    For i2 = 0 To List2.ListCount - 1
        List3.AddItem List1.List(i1) & List2.List(i2)
    Next
Next
